Your respiratory system is primarily set up to take advantage of two key processes: Bulk Flow and Diffusion.

1. Bulk Flow: This is the process that moves air in and out of the lungs. When you inhale, your diaphragm and intercostal muscles (the muscles between your ribs) contract, expanding your chest cavity and decreasing the pressure inside your lungs. This causes air to flow into your lungs. When you exhale, these muscles relax, reducing the size of your chest cavity and increasing the pressure inside your lungs, which forces air out.

2. Diffusion: Once the air is in your lungs, oxygen needs to get into your bloodstream, and carbon dioxide (a waste product) needs to get out. This happens through diffusion. In the alveoli (tiny air sacs in your lungs), oxygen in the air you've inhaled diffuses across the thin walls of the alveoli and into the surrounding blood vessels, while carbon dioxide diffuses from the blood into the alveoli, from where it can be exhaled.

So, your respiratory system is set up to take advantage of both bulk flow (to move air in and out of the lungs) and diffusion (to exchange oxygen and carbon dioxide between your lungs and your blood).
